Sushi Jambi is a sushi restaurant in Yeonnam, Seoul, serving aged hoe sushi and sushi sets. The Jambi Koborezushi pairs chewy flounder with aged kimchi and a sauce, and yellowtail sushi is also on the menu. Chawanmushi comes before the meal, and the C set includes 12 pieces of sushi. The dining room is white-toned, so lunch is quiet.
